RAILROAD-TRACK STRUCTURE.

SPECIFICATION forming part of Letters Patent No. 693,210, dated. February 11, 1902.

Application tiled November 21, 1896. Serial No. 613,025. (No model.)

To ctZZ whom t may concern.:

Beit known that VICTOR ANGERER, a citizen of the United States, residing at Philadelphia, Pennsylvania, and EDWARD SAMUEL, formerly a citizen of the United States, residing at Philadelphia, Pennsylvania, but now deceased, did during the lifetime of said ED- WARD SAMUEL invent certain Improvements in Railroad-Track Structures, of which the following is a specification.

The object of t-he invention is to provide a rail structure, such as a crossing or frog, with a hard-metal plate set in the center, this hardmetal plate being confined to those portions of the structure which have to sustain more wear than'the adjoining rails; and a further obj ect is to provide'a gradual change of bearing of the wheel from the hard metal to the softer metal, or vice versa. Heretofore it has been the practice to make the hard-metal centers of considerable length, so that portions of these hard-metal centers receive no more wear than the adjoining rails, thereby causing uneven wear within the center itself, and it further has been the practice to make the joint between the hard-metal center and the adjoining rails square or nearly square, thereby making an abrupt change from the hard metal to the softer metal of the rail, making in time an uneven track.

In the accompanying drawings, Figure l is a perspective View of a crossing structure illustrating the invention. Fig. 2 is a plan view. Fig. 3 is a longitudinal sectional view of Fig. l. Fig. 4 is a perspective view of the center plate.

Referring to Fg.l,whichillustrates a crossing structure in which the rail A crosses the rail B, it will readily be seen that the diamondshaped portion in the center is subjected to the travel on both rails A and B on one part, while the other parts have to sustain the traffic on a reduced width of bearing-surface It is necessary, therefore, to leave out or cut out the rails within this diamond-shaped space and insert a plate D, through which plate are cut grooves d to continue the flangeways in the crossing-rails.

The practice heretofore in use was to insert hard plates in the structure. These plates,

however, would extend beyond the diamondshaped space, and the parts within this space would wear faster than the portions outside of it, and ridges would therefore form where they cross the tread of the rail.

Referring again to Fig. 2, itwill be seen that a wheel traveling on rail A in the direc` tion of arrow 1 will at pointm on the tread part of the structure commence to leave the bearing on the head of the rail and gradually take a partial bearing on the hard center plate, until at a point opposite n it will bear only on the center plate. At point s it Will commence to leave the center plate and gradually take a bearing on the rail, until at a point opposite t it again has a full bearing on the rail. This will insure smooth running of the wheels and will tend to equalizethe wear, while in the old methods the abrupt change from a hard metal to a softer metal would quickly work a depressioninto the softer metal just beyond the-joint.

It will be understood that when the wear of the wheels is spoken of it not only refers to the vertical wear by the tread, but also to the side wear by the tlanges, both of which, as will be seen, are provided for in the hard center plate. j

l. The combination in a crossing structure,

, of the rails forming said structure, a diamondshaped plate mounted in that portion of the structure where the rails would cross each other, said diamond shaped plate having ilangeways cut therein forming four diamondshaped projections, substantially as described.

2. The combination in a crossing structure, of the rails forming said structure, a castmetal joint-block by which the rails are secured together, a cavity in the said jointblock, a hard-metal center plate mounted within saidcavity and having ytlangeways forming four diamond-shaped projections, substantially as described.

3. The combination in a crossing structure, of the rails forming said structure, the ends of the rails being cut at an angle, a cast block by which the rails are secured together, a diamond-shaped cavity formed in the block and by the rails, with a diamond-shaped hardmetal plate mounted in said-cavity and hav- IOO il b 693,210
